Sphenoorbital meningiomas (SOMs) are slow-growing tumors that originate from the sphenoidal wing and are associated with visual deterioration, extrinsic ocular movement disorders, and proptosis caused by hyperostosis of the lateral wall of the orbit. In some cases, the intracranial component is quite small or "en plaque," and the majority of the symptoms arise from adjacent hyperostosis. Craniotomy has traditionally been the standard of care, but new minimally invasive multiportal endoscopic approaches offer an alternative. In the current study, the authors to present their experience with the transorbital endoscopic eyelid approach for the treatment of 2 patients with SOMs and sphenoid wing hyperostosis. Clinical and radiological data for patients with SOMs who underwent a transorbital endoscopic eyelid approach were retrospectively reviewed. Surgical technique and clinical and radiographic outcomes were analyzed. The authors report the cases of 2 patients with SOMs and proptosis due to sphenoid wing hyperostosis. One patient underwent prior craniotomy to debulk the intracranial portion of the tumor, and the other had a minimal intracranial component. Both patients were discharged 2 days after surgery. MR images and CT scans demonstrated a large debulking of the hyperostotic bone. Postoperative measurement of the proptosis with the aid of an exophthalmometer demonstrated significant reduction of the proptosis in one of the cases. Persistence of intraconal tumor in the orbital apex limited the efficacy of the procedure in the other case. A review of the literature revealed 1 publication with 3 reports of the transorbital eyelid approach for SOMs. No measure of relief of proptosis after this surgery had been previously reported. The transorbital endoscopic approach, combined with endonasal decompression of the medial orbit, may be a useful minimally invasive alternative to craniotomy in a subset of SOMs with a predominantly hyperostotic orbital wall and minimal intracranial bulky or merely en plaque disease. In these cases, relief of proptosis and optic nerve compression are the primary goals of surgery, rather than gross-total resection, which may have high morbidity or be unachievable. In cases with significant residual intraconal tumor, orbital bone removal alone may not be sufficient to reduce proptosis.

Purpose. To evaluate perioperative risk factors for corneal abrasion (CA) and to determine current care for perioperative CA in a tertiary care setting. Methods. Hospital-based, cross-sectional study. In Operating Room and Post-Anesthesia Care Units patients, a comparison of cases and controls was evaluated to elucidate risk factors, time to treatment, and most common treatments prescribed for corneal abrasions. Results. 86 cases of corneal abrasion and 89 controls were identified from the 78,542 surgical procedures performed over 2 years. Statistically significant risk factors were age (P = 0.0037), general anesthesia (P < 0.001), greater average estimated blood loss (P < 0.001), eyes taped during surgery (P < 0.001), prone position (P < 0.001), trendelenburg position (P < 0.001), and supplemental oxygen en route to and in the Post-Anesthesia Care Units (P < 0.001). Average time to complaint was 129 minutes. 94% of cases had an inpatient ophthalmology consult, with an average time to consult of 164 minutes. The most common treatment was artificial tears alone (40%), followed by combination treatment of antibiotic ointment and artificial tears (35.3%). Conclusions. Trendelenburg positioning is a novel risk factor for CA. Diagnosis and treatment of perioperative corneal abrasions by an ophthalmologist typically require three hours in the tertiary care setting.

Medina. Approximately forty patients a day were Received for publication January 5, 1971 examined for 3 days. At the suggestion of the epidemiologist, the patients were numbered from 150 to 272, so that the memorizing of numbers would be reduced to a minimum. The studies performed on each patient are listed below.

The current literature on blue-blocking IOLs is contradictory. Studies have failed to conclusively prove that blue-blocking lenses provide photoprotection against age-related macular degeneration or cause any significant detrimental effects on visual function or circadian rhythms.

Hidrocystomas are benign, cystic lesions of eccrine and apocrine sweat glands. The literature on hidrocystomas is sparse, consisting of a handful of case reports and limited retrospective reviews. This is the first known bi-institutional, retrospective, chart review aimed to elucidate the demographics and basic clinical presentation of hidrocystomas. Medical records of adult patients with a pathological diagnosis of hidrocystoma from September 1, 2008 to August 1, 2015 in the Oculoplastic and Reconstructive Surgery Service at the Illinois Eye and Ear Infirmary (UIC) and Department of Ophthalmology of Weill Cornell Medical College (Cornell) were reviewed. Children under the age of 18 were not included. Data collection included: gender, race, age at diagnosis, laterality, location, total number of lesions, and recurrence. Results from both institutions were compared against each other and as a whole. A total of 107 patients were diagnosed with hidrocystoma on pathology. The mean age of diagnosis was 56 years (22-85). Hidrocystomas were diagnosed in 69 (64.4%) females and 38 (35.5%) males. Lesions were most commonly found in African American (37.4%), Caucasian (30.8%), and Hispanic (16.8%) patients combined across the two institutions with different patient populations. Lesions were largely unilateral (74.8%) and found on the lower lid (38.6%), lateral canthus (31.2%), upper lid (17.7%), and medial canthus (12.6%). Recurrences were seen in 2.3% of lesions. The majority of recurrences occurred in patients who identified their race as Hispanic (2/5) and Caucasian (3/5). Recurrences were seen in 2 males and 3 females. Apocrine and ecccrine hidrocystomas may be more common in female, African American, Caucasian, and Hispanic patients, presenting most commonly in adults in their mid-fifties. Lesions tend to be unilateral with lower lid lesions being the most prevalent location and medial canthus lesions being the least prevalent location for lesion growth. Recurrences may be most common in Hispanics and Caucasians and less common in African Americans. Although a precise recurrence rate cannot be determined at this time, our data suggests that the recurrence rate is low with current excisional methods.
